Israel conducted an airstrike inside Syria overnight near the border with Lebanon, hitting a convoy of trucks, US and regional officials said Wednesday.

The regional officials said Israel had been planning in the days leading up to the airstrike to hit a shipment of weapons bound for Hezbollah in Lebanon. They said the shipment included sophisticated, Russian-made SA-17 anti-aircraft missiles, which would be strategically "game-changing" in the hands of Hezbollah.

A US official said the strike hit a convoy of trucks.

SA-17 missiles are self-propelled and have the capacity to hit jets at a low altitude. The system's portability makes it harder to trace and enables it to surprise jets within its range. These attributes could jeopardize IAF jets should they operate against Hezbollah in Lebanon.

A former senior security official in Lebanon told the Washington Post that the attack involved a missile fired by an unmanned Israel aircraft at a truck the Lebanon-Syria border. There were no casualties, according to him. The strike was on the Syrian side of the border, said the former official, who still has close ties to Lebanon’s senior security team and said he was told about the attack by a high-ranking official.

He said the truck was carrying weapons, although it was unclear what kind of weapons. It also was not immediately clear whether the truck was being used by the Syrian military or by Syrian rebel forces, who have been locked in a brutal, bloody civil conflict for almost two years.

I think as the final days of Assad fall on Syria we will see more of these types of activities on both sides.

More attempts to transfer weapons to Hezbollah, and more actions by Israel to hit the trucks inside Syria.
